well, i've been playing about with the scales... this bike definitely isn't ww!

the isp is very heavy... unless someone makes a silly light usp top bracket, the only option here is simply to saw off the isp post and replace with a collar and lightweight seatpost (cinelli provide a collar specifically to allow you to do this with the frame).

the bike complete with cages and ultegra spd's is 7.7kgs on my bathroom scales.

have you considered cutting the ISP a few mm lower, making a slot, putting on the clamp, and using a cut down seatpost instead? It will retain the ISP but cut weight ala Time. I am considering doing this for my build.

Hmmm, that ISP cap is a touch on the heavy side.However the ISP forms a fairly prominent part of that frames overall aesthetic, with the extension of the paint finish. Of course, if you’re a dab hand with the humbrol you could replicate that on any seatpost you changed it for, but when something looks that good would you really want to change it!? As you mention, the weight saving isn’t going to be all that much at circa 100g, so considering there are greater savings to be made elsewhere I would personally be inclined to leave it as Cinelli intended, looks like a great ride!

i think i may be inclined to agree... i really don't want to cut the isp off and replace with a regular post, as i would lose this awesome look...

You may try to insert a normal 31,6 seatpost (cut of course) and a clamp. It may work...Just keep your money for lighter wheels. Don't spend them on brakes etc.

the bike was built to my own spec, so i'm not going to be in a hurry to change the wheels... i wanted clinchers and a 50mm aero section with alloy braking surface... for the money, i think i would struggle to get much lighter than the bullet ultras (oh, by the way, i didn't pay anywhere near GBP1k for them!).

i know that if i moved to tubs or went away from aero profiles, i could quite easily get into the realms of 1,000g wheelsets for much less money, but then my 95kgs (in my bday suit) bulk starts coming into play. i'm never going to be able to go the whole hog on a ww' build for this reason alone, so it is a case of balancing function with quality and durability.

Is there any chance that the ISP might not be able to take clamping forces? If Cinelli have the ISP topper working with expansion would having one that clamps on damage the frame? I know that Cinelli allow you to cut it down and use it as a normal seatpost, but maybe its only designed to take clamping forces lower down Just my 2c
